Altinity provides a managed platform and enterprise support for ClickHouse, an open-source SQL analytics database designed for real-time queries at petabyte scale.

Altinity, founded in 2017 by Alexander Zaitsev, is an independent commercial company providing enterprise services and managed infrastructure around ClickHouse, the open-source SQL analytics database. Robert Hodges joined as CEO in 2019, having previously led Continuent through a successful acquisition by VMware in 2014. The company raised a $4 million seed round from Accel Partners in October 2020 to build Altinity.Cloud, a managed service now deployed across AWS, GCP, and Azure.

Altinity is not affiliated with ClickHouse, Inc., which maintains the open-source project itself; instead, Altinity functions as a commercial custodian, contributing over 1,000 pull requests to the ClickHouse ecosystem while operating its own managed platform with flexible deployment options including bring-your-own-cloud (BYOC) and bring-your-own-Kubernetes (BYOK) models. As of mid-2025, the company operates with approximately 51 employees across four continents and reported $3.8M in annual recurring revenue. The company focuses on enterprise customers requiring real-time analytics at scale, with named deployments at companies including eBay, Cisco Umbrella, Vimeo, Twilio, Lyft, PostHog, and ChartMogul.

In 2025, Altinity released Project Antalya, a strategic initiative aimed at eliminating trade-offs between real-time database performance and data lake scalability. Key 2025 announcements include the launch of managed Apache Iceberg catalogs and compute swarms for Altinity.Cloud in July, enabling ClickHouse to query data stored in cheaper object storage while maintaining sub-second query performance. The company differentiates from ClickHouse Cloud by offering full access to open-source ClickHouse features, including experimental functionality, and avoids usage-based pricing in favor of allocated compute and storage models.

This flexibility lets organizations choose where and how they run ClickHouse.

How does Altinity handle real-time analytics at scale?

ClickHouse, which Altinity manages, is engineered for real-time SQL queries on massive datasets at petabyte scale.

This enables BI applications, monitoring dashboards, and analytics at enterprise scale.

What is Project Antalya?

Project Antalya is Altinity's 2025 strategic initiative to eliminate the performance versus scalability trade-off. It includes managed Apache Iceberg catalog integration and compute swarms, enabling ClickHouse to query cheaper object storage while maintaining sub-second query performance. This bridges real-time databases with data lake economics.
